Stator values

I Have recently rebuilt a SL900 but when I got it on the water it would not do over 3400 rpm. I beleve the problem is the rear spark plug is not fireing.
I tested the coil and stator I came up with the following values:
Primary coil windings:
PTO Black/Green to Black/White --18 ohms
CEN Black/Blue to Black/White --.5 ohms
MAG Yellow/Brown to Black/White --.5 ohms

Stator triger:
red 7.7 ohms
blue 7.7 ohms
green 1.8 ohms

Now I am fairly sure the coil is bad, but is it possible the stator may be a bad wire, or magnet?
I don't have a problem changing the stator with the update kit, but I need coils and I haven't been able to find a replacement. Is there any other coils that will work that are still being produced? Or, does anyone know where I can get a coil (new or used)?
The upgrade kit is too expensive if I can't get a coil.
